IMPROVEMENT IN APPARATUS FO R REGULATING RECIPROCATING MOTION.

' Specification forming part of Letters Patent No. 202,052, dated April2, 1878; application filed March 27, 1878.

To all whom it may concern:

Be it known that I, ALBION M. Room, of Boulder, Boulder county, State ofColorado, have invented a new and useful Improvement in Apparatus forRegulating Reciprocating Motion, which improvement is-fully set forth inthe following specification, reference being had to the accompanyingdrawings.

This improvement relates to a mechanism for imparting the percussiveblows by which reciprocation and agitation are given to the table. I

My improvement consists in the combination of a rod, one end of which ishinged to the table and the other end made vertically adjustable, andhaving an aperture through which passes an oscillating lever, the travelof the connecting-rod being regulated by raising or lowering it upon thelever. 1

Referring to the accompanying drawings, Figure l is a perspective viewof my improve ment. Fig. 2 is a detail side view, partly in section,showing the adjustable blocks against which the lever impinges.

A is a post, to which the apparatus is secured. B B are bracketsthereon, supportin g the journal-boxes O and D of the shafts E and F.The shaft E carries a balance or fly wheel, G, a cone-pulley, H, and acog-pinion, I. The cone-pulley receives a belt by which the mechanism isdriven, and the pinion I eugages with a spur-wheel, J, upon the shaft F,to cause the rotation of said shaft. The spurwhcel J has a number ofholes, jj, at different distances from the center, for the insertion ofa wrist-pin, K, so as to give a means for regulating the throw of theconnecting-rod L, which connects the wrist-pin with the lower end of thelever M. Thus, to lessen the vibration of the lever M, the wrist-pin Kis changed to a hole, j, nearer to the center of the spurwheel.

The lever M is' fulcrumed at N, and passes between the blocks secured tothe connectingrod 0, whose other end (not shown) is connected to theore-concentrating table. The lever M is shown as passing through anaperture in the connecting-rod O, and this is my preferred mode ofconstruction; but the same end would be accomplished (though in a lessperfect way) if the blocks were attached to the side of theconnecting'rod. The blocks consist of an adjustable metallic box, P,with an elastic pad, Q, against which the side of the lever M impinges.The box P is made adjustable by the insertion of a shim, R, behind it.

The distance between the pads Q Q is greater than the breadth of thelever M, so that the reciprocation of the connecting-rod 0 shall not beby a continuous motion, but that it shall have a jerking motion impartedto it by the blow of the lever M against the pad.

It will be understood that the movement of the connecting-rod 0 willvary according to its position upon thelever M, and to govern suchposition I attach to the end of the connecting-rod a cord, S, whichpasses upward and gives support to the end m, so that by means of thecord this end is supported at any desired altitude.

It will be observed that the lever M is narrowed at the upper end, sothat when the end m is raised to its upper position no motion isimparted to the connecting-rod by the lever M in its oscillation.

I have not shown or described any particular form of ore-concentratingtable or pans, because my mechanism is applicable to any where areciprocating motion is required.

I will now briefly review the means for regulating the movement of themechanism. The speed is regulated by changing the belt upon thecone-pulley H. The oscillation of the lever M is regulated by theposition of the wristpin K in the spur-wheel J, and the length of strokeof the connecting-rod O is regulated by the position on a vertical lineof the end m of said rod.

I claim- 1. The combination of lever M and rod 0, adjustable thereon bymeans of a cord, S, substantially as and for the purpose set forth.

2. The combination of rod 0, cord S, lever M, rod L, and crank-wheel J,substantially as and for the purpose set forth.

3. The combination of rods 0 and L, lever M, crank gear-wheel J, withadjustable wristpin K, pinion I, shafts E and I cone-pulley H, andfly-wheel G, substantially as set forth.

4. In combination with the rod 0 and lever M, the blocks P Q, to receivethe impingement of the lever, substantially as set forth.
